crash-mcp · Summary

CRASH is an MCP server for structured reasoning with step validation, branching, and confidence tracking.

filesystem · Use cases

Enable AI models to read and write project files during development
Allow Claude or other MCP clients to browse and analyze codebases
Provide secure sandboxed access to specific directories for content generation

crash-mcp · Use cases

Complex multi-step problem solving in software development
System design with multiple architectural considerations

Installation

Using NPX

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem",
        "/path/to/allowed/directory"
      ]
    }
  }
}

Using Docker

{
  "mcpServers": {
    "filesystem": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "--mount", "type=bind,src=/path/to/allowed/dir,dst=/projects/allowed/dir",
        "mcp/filesystem",
        "/projects"
      ]
    }
  }
}

Quick Setup

Most MCP clients use this JSON configuration:

{
  "mcpServers": {
    "crash": {
      "command": "npx",
      "args": ["-y", "crash-mcp"]
    }
  }
}

Configuration by Client

| Client | Setup Method | |--------|-------------| | **Claude Code** | claude mcp add crash -- npx -y crash-mcp | | **Cursor** | Add to ~/.cursor/mcp.json | | **VS Code** | Add to settings JSON under mcp.servers | | **Claude Desktop** | Add to claude_desktop_config.json | | **Windsurf** | Add to MCP config file | | **JetBrains** | Settings > Tools > AI Assistant > MCP | | **Others** | Use standard MCP JSON config above |
